After owning everything from a Big Al to a T-Bird and a few custom made basses, and well over a dozen Ps and Js - I bought myself a Ric, and it's become my number one. But that's only the first reason I think you should buy a Ric

.
The above is a more important reason.
You are a talkbass member. I'll assume you therefor know more about basses, their prices, and their value than 80% of the bass players out there (contrary to popular TB belief, it's a very small percentage of bass players that are active TB members). And even being a part of this great community, and being informed - you believe you can't afford a new Rickenbacker, and are willing to pay $1200-1300 for a used one.
A brand new 2016 Rickenbacker 4003 can be easily had for the price you're willing to pay for a used one. Other models you can get for even less.
The vast majority of people buying Rics are willing to pay much more for a used one, than they can get a new one for. The day I bought mine brand new, someone on Talkbass was selling the same exact bass used - for $100 more than I paid new. And I'm pretty sure he sold it.
My train of thought was derailed by a phone call

... and I'm having a rough time finishing up now here. Anyhow... If you want info on how to get a Ric at that price, I've outlined it a bunch of times before here. I can find it later, or PM you if you're interested. Others here have gotten them even cheaper than me (I paid somewhere around 1300 for mine), so maybe they can help, too.
Anyhow, last thoughts on this - if you check Rickenbacker reviews here, it seems the past 2 years have been EXCELLENT years for Rics. Just about everyone picking a new one up is in love. 20 - 30 years from now I think that's going to count for something. And regarding the bass itself, it is an absolute tone monster, capable of much more than I ever thought it was. You can get the classic Chris Squire tones out of it (tones I never even use on mine), and pretty much any tones you can get with a P or J bass. I've used my Ric in a Zep tribute, and it worked awesomely. A year ago I'd have thought someone insane to bring a Ric to a Zep gig.
Anyhow, that's my take on it. I say Ric.
